G'day James.Looks similar to those panels you used to see at the big car shows.The big thing in the late 80's for air brush artists to advertise their work, try and get some new business.I remember some bonnets and tailgates on stands with this type of work.Usualy the guy would be doing some kind of artwork while ppl watched.Maybe thats what you have there........maybe....looks cool though.Its XD-XF????

Having a good look , you never know John, it could be. It was always my first thought but i never had the photo of the 2 near each other to compare, they both have the chrome trim around the wheel arch, pity my camera was not great way back then.
